Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

open access: yescMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Interrelationship of hydrology, microbial colonisation and hydrometallurgy in a simulated chalcopyrite heap leach

open access: yes, 2008
Includes bibliographical references (leaves 104-115).Chalcopyrite is the most abundant primary copper sulphide mineral found worldwide. As copper grades of ores available for extraction decrease, heap bioleaching is gaining interest as a potential ...

Lanmodulin‐Decorated Microbes for Efficient Lanthanide Recovery

open access: yesAdvanced Materials, Volume 37, Issue 10, March 12, 2025.
Bio‐scaffolded lanmodulin (LanM) on E. coli is developed as a simple, effective material for repeated capture and release of rare earth elements (REEs). Over 80% of four REE cations are captured, even in the presence of excess competitive ions. The material can be employed in a filtration flow‐through system with a capture capacity of 11.8 ± 0.9 mg g−1

Iron and sulfur utilisation patterns in chemolithotrophic cultures

open access: yes, 2012
In this study, the growth and behaviour of chemolithotrophic organisms in the presence of both ferrous and tetrathionate ions was investigated. Given the impact of chemolithotrophic metabolic activity upon the chemistry and leaching of mineral sulfide ...

Arsenic-microbe-mineral interactions in mining-affected environments [PDF]

open access: yes, 2013
The toxic element arsenic (As) occurs widely in solid and liquid mine wastes. Aqueous forms of arsenic are taken up in As-bearing sulfides, arsenides, sulfosalts, oxides, oxyhydroxides, Fe-oxides, -hydroxides, -oxyhydroxides and -sulfates, and Fe-, Ca-Fe-
